600g/1lb 5oz parsnips, peeled and roughly chopped
4 tbsp olive oil
50g/1¾oz lactose free butter
225g/8oz celery, thinly sliced
1 tbsp dried rosemary
750ml/1¼ pint lactose free milk
750ml/1¼ pint low FODMAP stock
salt and freshly ground black pepper
Preheat the oven to 200C/400F/Gas 6. Place the parsnips on a roasting tray with half the olive oil and toss to coat.
Roast in the oven for 15 minutes until golden-brown and tender, then remove and set aside.
Heat the remaining olive oil and the lactose free butter in a large saucepan. Add the celery and dried rosemary, cover and fry gently for 3-4 minutes.
Add the roasted parsnip and the remaining ingredients. Bring to the boil.
Reduce to a simmer and cook for five minutes, or until the parsnip is very soft.
Transfer to a blender and pulse until smooth. Season to taste with salt and freshly ground black pepper.
